Anyone who thinks Crea isn't the boss is crazy, no one is taking orders for Amuso, So even if he hasn't technically said im stepping down does it matter, wouldn't you consider the person boss is making every decision for that family, To be a boss of a family from the inside you need a strong support system on the outside of people loyal to you he didn't have that before he went away never mind 20 years down the line, So Crea is the boss, and to answer the question Amuso has no control over the families administration
